Moving to Mexico? ¡Felicidades! To make the most of your time in the country, you’ll need to find out how to handle your money there. In Mexico, that involves several different numbers and codes, which can get a little confusing. Here’s a guide to which is which, and what each of them is for.

What’s a CLABE number?

A Clave Bancaria Estandarizada (CLABE) is a standard bank account number in Mexico. Its name translates to ‘standardized banking code’. Every Mexican bank account has a unique CLABE. They’re needed in particular for sending and receiving money between accounts.

What’s the structure of a CLABE number?

CLABE numbers have 18 digits, divided into 4 sections like this: AAABBBCCCCCCCCCCCD.

The first three digits denote the bank, and the second three digits refer to the location of the bank. The 11-digit third section is the bank’s own code to identify each of its customers unique account. The final digit is a control, which checks the validity of the previous 17 digits.

Here is an example of a CLABE number:

014027000000000008

014 is the code for Banco Santander; 027 is the code for Tijuana; the 0s are the section that identifies the account; and the 8 at the end is the checking digit.

How do I find my CLABE number?

Check with your bank, as the best method might vary. But it should be on official documentation from your bank such as a bank statement, or else in your online banking portal. Give your bank a call if you can’t find it anywhere.

You can check your number online with a CLABE validator.

How do I find a bank code (ABM) in Mexico?

ABM stands for Asociación de Bancos de México (Banking Association of Mexico). That’s the organization that links all the Mexican banks together.

The ABM code or bank code is the three-digit code that identifies the bank itself. It’s the first three digits of your CLABE.

Here are the 10 largest banks in Mexico and their ABM codes.

What’s an RFC number in Mexico? And what does it stand for?

RFC stands for Registro Federal de Contribuyentes, and the clave RFC (RFC number) is a Mexican tax identification number. It’s issued by the Mexican Tax Administration Service (Servicio de Administración Tributaria).

RFCs are 13 digits long for individuals, 12 for companies, and they’re made up of letters and numbers. The first 4 digits for individuals, or 3 for companies, are taken from the name, then there are six numbers denoting the date of birth or when the business was founded, and the end digits are check digits.

What are the required documents to get an RFC number?

As an individual, you’ll need your CURP (see below) or birth certificate, proof of address, and official ID. Businesses need to prove they’re incorporated and that the person registering the company is authorized to do so.

What is CURP in Mexico? And what does it stand for?

A CURP is a Clave Única de Registro de Población (Unique Population Registry Code). It’s an 18-digit social security number for people living in Mexico. The 18 characters combine information deriving from your name, date and place of birth, and gender to create a unique code.

You’ll need this number for all manner of things, from applying for an RFC (see above) to applying for jobs or getting a driving license - or even opening a bank account.

The code is issued on a card known as a CURP card.

Will you get a physical document? What if you lose it?

You should get a printed document, although it might just be a piece of paper - laminating it to keep it safe is a good idea. If you lose it, you can look the number up online and print another one.

Sending money to Mexico from abroad? TransferWise could help you save money.

Getting set up in Mexico is one thing, but dealing with your finances in both Mexico and your home country can be just as tough. Transferring money internationally through a bank or a normal transfer service can mean suffering a markup on the exchange rate of 4-5%. Rather than losing out on that much money, using TransferWise can make the whole process far smoother by only charging the mid-market exchange rate - the only real rate there is - and one small fee stated upfront. That could end up saving you a lot of money.

And with a borderless multi-currency account, you can store your money in dozens of different currencies as well as the Mexican peso and use the debit card to access your money with ease. So if you have a lot of payments to make, this is the perfect way to do it without having to pay all manner of extra fees. It’s particularly useful at the start of your time in Mexico, while you get set up with a CURP.

Take a look now at how much cheaper TransferWise is than a bank transfer.

Good luck as you sort out all of your Mexican details!
