Information Required to Sign Up

Federal law requires that all financial institutions obtain, verify, and record information that identifies each person who opens an account.

Current credit card regulations require our customers to be at least 18 years of age, so you'll need to be 18 or older to create a Square account. 

The following information is required to activate a Square account:

Information Required?
Social Security number Yes
Credit check No
US-based bank account* Yes
Date of birth Yes
US mailing address** Yes
EIN*** Optional
Merchant bank account


PCI assessment****


* A US bank account is required for your funds to be deposited.

** A PO Box can be used for shipping but not as a home address for activation.

*** An EIN is not required but is recommended for businesses and organizations.

**** Square meets Level 1 PCI Data Security Standards.

Note: The option to enter an EIN does not replace the SSN requirement. If you're not able to provide the information above, you won't be able to accept card payments, but you can still use Square to track cash payments and provide your customers with email and text receipts.

Social Security Number Requirement

We are required by banking industry regulations and federal law to ask for the Social Security number, date of birth, and full name for each of our primary account holders. If you are Mobile Staff, or have been added as an employee, you will not need to provide this information. 

Even if you plan on using Square as a business, there is no way to create a Square account without providing a valid SSN.

For tax purposes, you can also include your Employment Identification Number during signup. Having your Square account associated with your business EIN is advantageous when it comes to completing your taxes, and it helps us identify you as a business. This information also enables us to negotiate better rates and more features with our underwriting partners for all Square merchants.

Choose a Business Type

During the signup process you'll need to classify how you'll use Square by selecting your business type or Merchant Category Code. Square will use this information to provide you with the best features to help you grow your business. If you've already set your business type and would like to change it, contact us
