Mexico: know before you go

  • Prices can be affected by season. Many hotels raise their prices at peak times such as summer, Christmas and Easter, especially in areas like Acapulco and Cancun

  • Local market produce is much cheaper and often much fresher than in restaurants, but you may need to barter. Locally owned hotels and restaurants are also much less expensive than those targeting tourists

  • Agree taxi fares up front – many drivers don't use meters, so agree on a price before you get in

  • Tips on tipping – taxi drivers don’t expect tips, but it's customary to tip restaurant waiters 10-15% of your bill, unless service is included

Some common questions

  • The Mexican peso is the official currency of Mexico. It is issued by the Bank of Mexico and is one of over 60 currencies available commission-free from the Post Office. You can buy your pesos online or buy currency for Mexico in branch.

    Pesos and dollars have common origins, so both use the $ symbol. You may see it as MX$ or $MN to distinguish it from the US dollar (MN stands for Moneda Nacional, or National Currency). The abbreviation for Mexican peso is MXN.

    As with the dollar, the Mexican peso is subdivided into 100 cents.

  • The Mexican peso is used exclusively by Mexico and no other country or territory. But it shares its origin with the dollar used across the border in the USA.

  • You can buy Mexican pesos online or in participating branches at the Post Office. Find your local branch. It’s easy, commission-free and we’ll give you a competitive rate.

    You may get a better rate online than in branch, and the rate gets better the more currency you buy. You’ll also save money if you can wait until the Mexican peso exchange rate is good.

    Order with click and collect and, if it’s before 3pm on a working day, you can pick it up in any branch the next working day. Or we’ll deliver currency to your home using Royal Mail Special Delivery Guaranteed® by 1pm.

  • The highest-value denomination in the Mexican currency is the 1,000 peso banknote. Other notes available are worth 20, 50, 100, 200 and 500 pesos.

    The highest value coin is the 20 peso, though it’s rare. There are also coins worth 1, 2, 5 and 10 pesos. You may find others worth 5, 10, 20 and 50 centavos (or cents). Coins worth less than 50 cents are also rare.

    Many traders won't have any change, so carry some smaller notes and coins if you're shopping away from the big stores.

Remember, if you travel against official advice your travel insurance policy may not cover the trip.
