Check Amazon Account Registration
Verify whether a phone number or email is registered on Amazon.
Amazon's phone-linked accounts span its retail marketplace, Prime membership, and device ecosystem (Alexa, Kindle, Fire TV), making registration a broad e-commerce signal rather than a niche one. CheckNumber's Amazon checker confirms whether a phone number belongs to a registered Amazon account, useful for qualifying e-commerce leads or cleaning a list before retail-focused outreach, without ever logging in, messaging, or contacting the user.

Amazon FAQ
Can I check whether numbers or emails are on Amazon in bulk?
Yes. Upload a CSV of phone numbers or email addresses, or call the REST API, choose the matching task type, then download a result file with a registered or not-registered verdict for each record. You are billed only for successful checks.
Do you check by phone number, email, or both?
Both. The number task type checks phone numbers and the email task type checks email addresses against Amazon registration, so you can use whichever identifier your list contains.
Does the check contact or notify the Amazon user?
No. The check is passive and reads registration signals only. Nothing is sent to the number or email, and the account holder is never contacted, logged in to, or notified.
Is there a free trial?
Yes. New accounts receive 1,000 free checks on signup with no credit card, and every check is pay-as-you-go with no monthly fee, and the credits you top up never expire.
