US Dollars, Amex and US Cards in Guatemala: What the Law and the Card Rules Actually Say

In short: Guatemala’s answer to “do I need quetzales?” is set by two statutes, not by custom. The Ley Monetaria (Decreto 17-2002, Art. 6) makes the quetzal the unit of account and means of payment in every monetary transaction unless the parties expressly agree otherwise, and gives it discharging power over debts. The Ley de Libre Negociación de Divisas (Decreto 94-2000, Art. 1) makes disposing of, holding, contracting, collecting and paying in and with foreign currency free. Together: paying in US dollars is lawful when both sides agree, and no merchant is obliged to take them. On cards, the binding text is not Guatemalan law at all — it is the Visa Core Rules, which prohibit card surcharges and card minimums with no Guatemala exception, permit merchants in this region to ask for your ID, and require that dynamic currency conversion be optional, unpre-selected and expressly agreed.

This page is about spending — what happens at a till, a hotel desk, a card terminal. If your question is which card to open before you fly, that is ATM cards that work in Guatemala. If it is whether your phone apps work here, that is US payment apps in Guatemala. Today’s Banco de Guatemala reference rate is Q7.62 (2026-08-11); the history is on the exchange rate tracker.

What is settled, and by which instrument

The law: the quetzal is the default, dollars are a permission

Two Guatemalan statutes, both published by Banco de Guatemala, do all the work here — and most travel writing on this subject cites neither.

Ley Monetaria, Decreto Número 17-2002 del Congreso de la República. Article 1 establishes the unit: “La unidad monetaria de Guatemala se denomina Quetzal. El símbolo monetario del Quetzal se representa por la letra ‘Q’.” Article 6, headed Curso de la moneda, is the operative one:

“Salvo que las partes convencionalmente y en forma expresa dispongan lo contrario, el Quetzal se empleará como moneda de cuenta y medio de pago en todo acto o negocio de contenido dinerario, y tendrá poder liberatorio de deudas.”

In plain terms: unless the parties expressly agree otherwise, the quetzal is the unit of account and means of payment in every monetary transaction, and it discharges debts. The same article adds that courts and administrative bodies must faithfully respect and enforce what the parties agreed, and that any natural or legal person may freely agree to be paid fees, salaries, wages or commissions in foreign currency.

Ley de Libre Negociación de Divisas, Decreto Número 94-2000. Article 1, Sistema cambiario, opens:

“Es libre la disposición, tenencia, contratación, remesa, transferencia, compra, venta, cobro y pago de y con divisas…”

and continues that holding and managing foreign-currency deposits and accounts is equally free, in domestic banks and abroad.

The reading these two produce together is the answer to the question people actually ask. Paying in dollars in Guatemala is not a grey area and not a favour — it is expressly free. But the quetzal is what discharges a debt by default, so nothing obliges a merchant to accept your dollars, and a shop that says “solo quetzales” is not breaking any rule. We looked for an instrument imposing a duty to accept foreign currency and found none as of 2026-08-11.

Where US dollars are documented as working

Two foreign governments publish specific, checkable statements about dollars in Guatemala, and both are narrower than the internet’s usual claim that “dollars are accepted everywhere”.

• Global Affairs Canada, Guatemala travel advice, Money section: “The currency of Guatemala is the Guatemalan quetzal (GTQ).” “You cannot exchange Canadian dollars in Guatemala.” “U.S. dollars may be exchanged for local currency at most major banks.” Note what that says: dollars are exchangeable at major banks, which is a different claim from dollars being spendable at merchants.
• U.S. Embassy in Guatemala, consular payment methods: “In person, you may pay in cash (U.S. dollars or Guatemalan quetzales) or by credit card.” A concrete, documented place where both currencies are taken — the Embassy’s own cashier.

Neither government publishes a merchant-level acceptance claim for US dollars in Guatemala, and neither do we. For the bank-window side of the exchange question — which bank offers what spread — see best bank for USD exchange in Guatemala.

Amex versus Visa and Mastercard

The honest answer here is a shape, not a percentage.

What is published: the U.S. Embassy in Guatemala maintains a Credit Cards page listing “Credomatic & American Express” offices “available for credit card cash withdrawals or Guatemalan-issued credit card replacements”, requiring a valid passport, open Monday to Friday, 8 a.m. to 6 p.m. The page lists offices in Guatemala City (Zona 9, Zona 10, Zona 11, Zona 1), plus Quetzaltenango (Monday-Friday 9 a.m. to 6 p.m., Saturday 9 a.m. to 1 p.m.) and Santa Lucía Cotzumalguapa, Escuintla (Monday-Friday 9 a.m. to 6 p.m.). The same page states that “Bank cards using the Cirrus networks (Pronto in Guatemala) are accepted”, and that “A replacement credit card cannot be issued in Guatemala without the proper authorization of a bank in the United States.”

What is not published: no Guatemalan merchant-acceptance figure for American Express, Visa or Mastercard exists from American Express, from Visa, or from Guatemala’s Superintendencia de Bancos, as of 2026-08-11. Every “Amex is accepted at X% of places in Guatemala” number in circulation is unsourced. This page will not add another one.

What that leaves is a network fact rather than a coverage claim: American Express card servicing in Guatemala runs through Credomatic, which the U.S. Embassy names as the paired entity, and the network of physical service offices is concentrated in Guatemala City with two provincial locations. Our ATM fee comparator carries a hand-checked view of which ATM networks take which brands; its figures are a person’s reading of bank material, dated on the page, not a published tariff.

Dynamic currency conversion: the rule is that it is your choice

When a Guatemalan terminal or ATM offers to charge you in dollars instead of quetzales, that is Dynamic Currency Conversion (DCC), and it is governed by the card networks’ rules rather than by Guatemalan law. Visa publishes its rulebook openly.

Visa Core Rules and Visa Product and Service Rules, edition 18 April 2026, Section 5.8.9.2, “Dynamic Currency Conversion (DCC) – Merchant, ATM, and Branch Requirements” (ID# 0003100), requires a merchant, ATM acquirer or branch offering DCC to comply with all of the following — quoted:

• “Inform the Cardholder that DCC is optional and not use any language or procedures (for example: pre-selecting the DCC option) that may cause the Cardholder to choose DCC by default”
• “Ensure that the Cardholder expressly agrees to DCC”
• “For a Transaction in a Card-Present Environment, display the information specified in the DCC Guide to the Cardholder only on a customer-facing screen or handheld Acceptance Device.”
• “For a Transaction in a Card-Present Environment, require the Cardholder to expressly agree to DCC by directly interfacing with a customer-facing screen or handheld Acceptance Device.”
• “Not misrepresent, either explicitly or implicitly, that its DCC service is a Visa service”
• “Offer DCC in the Cardholder Billing Currency”
• “Not impose any additional requirements on the Cardholder to have the Transaction processed in the local currency”
• “Not convert a Transaction amount in the local currency that has been approved by the Cardholder into an amount in another currency after the Transaction has been completed but not yet entered into Interchange”

A footnote confirms this applies to ATM acquirers offering DCC on Cash Disbursements, not just shop terminals. The preceding rule, 5.8.9.1 (ID# 0025740), requires the acquirer to be registered and certified for DCC under Visa’s DCC Guide before processing any such transaction.

Three things follow, and none of them require us to publish a markup number. The rule says DCC must be optional; it says the option must not be pre-selected; and it says the merchant must not impose any additional requirement on you to have the transaction run in quetzales. The Visa Rules do not publish a DCC markup percentage, and no Guatemalan authority publishes one either — so any “DCC costs you 4-8%” figure, including ones on comparison pages, is not sourced to a rule. What the rule does establish is that the conversion, if it happens, is one you were required to be asked about.

Card surcharges, card minimums, and the ID request

These three come up constantly at Guatemalan tills and all three are answered in one place.

Surcharges. Visa Core Rules 1.5.5.2 (ID# 0006948): a merchant “must not add any amount over the advertised or normal price to a Transaction, unless applicable laws or regulations expressly require that a Merchant… be permitted to impose a surcharge. Any surcharge amount, if allowed, must be included in the Transaction amount and not collected separately.” The rule then names its own exceptions: the AP Region (New Zealand), the Canada Region, and the US Region and US Territories. There is no LAC Region or Guatemala exception.

Minimums. Visa Core Rules 1.5.5.1 (ID# 0026405): a merchant “must not establish a minimum or maximum Transaction amount as a condition for honoring a Card”, with exceptions only for a transaction on a US-issued credit card at a US merchant, and for certain European Economic Area or UK domestic transactions. Again, no Guatemala carve-out.

Identification. Visa Core Rules 1.5.5.3 (ID# 0027481): the default is that a merchant “must not request Cardholder identification as a condition of purchase” — but the LAC Region is expressly carved out: “A Merchant that suspects fraud in a Face-to-Face Environment may request Cardholder identification. If the identification is expired or does not match the name on the Card, or if the Cardholder does not provide identification, the Merchant may decide whether to accept the Card.” Guatemala is in Visa’s LAC Region. The passport request at a Guatemalan counter is therefore inside the rules, and the merchant may decline the card if you do not produce ID.

Scope note: these are Visa’s rules. Mastercard and American Express publish separate rulebooks that this page did not check, so nothing above should be read as describing a Mastercard or Amex transaction.

Torn and marked bills: the published silence

This is the claim that circulates hardest and has the least behind it, so here is exactly what we established.

Ley Monetaria, Decreto 17-2002, Art. 8 (Amortización y canje) does set a note-condition standard — for national currency only. Banco de Guatemala must amortise and exchange for new national notes or coins those national pieces “deterioradas por el uso, que resulten inadecuadas para la circulación”. Its stated limits: Banguat “no tendrá obligación de canjear los billetes cuya identificación sea imposible, o aquellos que hayan perdido más de dos quintas partes de su superficie”, nor coins that are unidentifiable or that show “señales de limaduras, recortes o perforaciones”. Such pieces are seized and withdrawn from circulation. The article does not mention foreign banknotes at all.

Ley de Libre Negociación de Divisas, Decreto 94-2000, Art. 1 makes foreign-currency dealing free but sets no condition standard for foreign notes.

So: no published Guatemalan instrument found, as of 2026-08-11, governs whether a bank, casa de cambio or merchant must accept a torn, taped, written-on or marked US banknote. Refusal is a commercial practice of the individual institution — very widely reported by travellers to Guatemala, and consistent with practice across the region, but not a rule anyone publishes. We are reporting the absence rather than dressing a traveller anecdote as a regulation. If Banguat, the Junta Monetaria or the Superintendencia de Bancos publishes such a standard, it is not in either monetary statute, and we did not find it elsewhere.

ATM caps and per-bank fees: the table we are not printing

Withdrawal caps and per-bank ATM fees are the single most rot-prone class of number in this whole subject, and Guatemalan banks make them hard to source. What we actually checked on 2026-08-11:

That is the honest state of the source. This page therefore publishes no per-bank ATM fee, no withdrawal cap, and no “average ATM fee” — an average computed over unpublished numbers is a fabrication with a decimal point on it. Our Guatemala ATM fee comparator does carry figures, and it discloses on its own face that they are hand-checked from bank material rather than scraped; read them as exactly that, with the date attached.

The one card-relevant figure a foreign government does publish: Global Affairs Canada states that “Some ATMs will accept Canadian debit cards with a four-digit PIN. Canadian debit cards with a five-digit PIN are not accepted.” That is a PIN-length constraint, not a fee.

Where cash is genuinely the answer

Two documented anchors, and then an honest gap.

Documented. Global Affairs Canada, on medical care in Guatemala: “Physicians and hospitals often expect immediate cash payment for medical care, though most private hospitals also accept credit cards.” And the UK Foreign, Commonwealth & Development Office, in its Guatemala travel advice, notes that pre-paid taxi vouchers can be bought from the office of INGUAT, Guatemala’s tourism institute, in the airport arrivals terminal — a cash-side workaround published by a government rather than a blog.

The gap, stated plainly. No Guatemalan instrument obliges any merchant or transport operator to accept cards, and no authority publishes a card-acceptance rate for municipal markets, extraurbano buses, tuk-tuks or rural comedores. We looked; there is no INGUAT, SIB or Banguat dataset behind the familiar “bring cash for markets and buses” advice. The legal backstop is the one at the top of this page: under Ley Monetaria Art. 6 quetzales discharge the debt by default, and card acceptance is a contractual arrangement each business chooses. Everything beyond that is observation, not a published figure, and we are not going to present it as one.
