What Walmart uses your number for
- Every Walmart account needs a mobile number that can receive texts, verified with a one-time code.
- You can sign in with a one-time code sent to your phone, alone or on top of your password.

Why the line type matters

MercuryQuestions
Can one number be on two Walmart accounts?
No. A phone number can only be linked to one Walmart account at a time, and verifying it on another account removes it from the first.
What if I can't open my email to change my number?
Walmart sends the passcode for a phone change to the email on your account. Its help says that without access to that email, you'll need to set up a new account to keep shopping.
Can I sign in to Walmart without a password?
Yes. Under Account, then Personal info, you can choose how you sign in: a one-time code to your phone or email, or a password plus a code.
Do I need to live in the U.S.?
No. TwinNumber works from 150+ countries with just a browser and an internet connection.
Is TwinNumber affiliated with Walmart?
No. We test our numbers with popular services and publish the results. Walmart is a trademark of its owner.
What if a code doesn't arrive?
Request a new code, then check your inbox and notification settings. If it keeps failing, contact us and we'll look into it.
