Interac^® verification service

What is Interac^® verification service?

Interac^® verification service helps verify your identity to enable access to Costco digital membership services. Interac^® verification service connects trusted sources that Costco members already have and use, like a financial institution, which can help verify their identities with Costco.

Why does Costco use Interac^® verification service?

Using the Interac^® verification service allows Costco members to quickly access Costco digital membership services in a convenient, secure and private way. No need for in-person visits to complete your membership verification: just use the personal information that you have already consented to and provided to your financial institution to verify your identity, gaining quick access to Costco membership services.

Why does Costco ask me to verify my identity?

To access your Digital Membership Card or other digital membership services, Costco members need to verify their identity before being granted access. Originally, the verification process was completed by an in-person visit or by answering knowledge-based questions. Now, once verified with Interac^® verification service, you can use your Digital Membership Card or renew your membership online, all from the comfort of your own home.

How does Interac^® verification service keep my personal information safe?

The Interac^® verification service uses strong, leading-edge technology with bank-grade security and protection to help protect your personal information from being identified, accessed or misused. Interac^® verification service has no access to the credentials you use to log in and your personal information is not stored by Interac^® verification service. You always stay in control by choosing when to share your information and with whom. Costco won't know the name of the financial institution you are using to verify your personal information with and the Interac^® verification service network won't be exposed to your personal information.

Are there any additional costs to using Interac^® verification service?

No. The use of the Interac^® verification service web service and download of the Interac^® verification service app are free. Data rates may apply.

Why am I returning back to the Costco home page or seeing a blank white page after I have completed the authentication flow using the Interac^® verification service app?

If this occurs, restart the identity verification process on the desktop browser (non-Safari browsers are currently enabled for Interac^® verification service verification).

I don't want to use Interac^® verification service to verify my identity with Costco. Is that still possible?

Yes. The in-person verification process is still available to members. Simply visit the Membership Counter at your local Costco warehouse.
