Managing your Amazon Store Card account

Co-branded cards always involve a retailer and a bank, and the Amazon Store Card is a particularly confusing example because the retailer is also where the card is used. Here is who does what.

The pattern is the same as the Prime Visa — the retailer sells it, the bank owns it — but the bank is different. If you hold both Amazon cards you have two credit accounts at two banks reached through the same shopping site, which is exactly the confusion the every-card explainer exists to clear up. The Prime Visa version of this page is here.

This card’s purchase APR is reported at 29.49% variable (Firstcard — Amazon Visa vs Store Card, secondary source, verified 2026-08-11). That is high enough that the difference between two autopay settings is the difference between a card that pays you and a card that costs you.

Autopay on the full statement balance means no interest on purchases, ever. Autopay on the minimum payment keeps the account current and charges you the APR on everything else, month after month, while nothing looks wrong. Both options sit in the same dropdown.

The arithmetic on what that costs — and how quickly it consumes the 5% — is on the interest rate page. The short version is that a few hundred dollars carried for most of a year wipes out a year of rewards on typical Amazon spending.

Two practical notes. Make sure the funding account will actually have the money: a returned payment is worse than a late one. And check that autopay covers what you expect it to cover when a financing plan is running, because a plan installment and a revolving balance are two different lines on the same account.

An Equal Monthly Payments plan is a 0% APR plan that splits an eligible purchase into equal installments — reported as 6 months on $50–$599.99 and 12 months on $600 and above (Firstcard — Amazon Visa vs Store Card, secondary source, verified 2026-08-11). Because a plan has its own schedule, an account with one running is genuinely more complicated to read than an ordinary credit card statement.

Three things to check each month rather than glancing at one total. What the plan installment is and when it is due. What the ordinary revolving balance is, separately. And whether the minimum payment shown covers both, or only one of them.

This is also the reason a financed purchase consumes your available credit in the ordinary way. On the typically small credit line, one plan can occupy most of the account until several installments have cleared.

The good news is that the structure you are managing now is the safe one. Synchrony stopped offering deferred-interest promotional financing on new Amazon Store Card purchases; Equal Monthly Payments remains (Firstcard — Amazon Visa vs Store Card, secondary source, verified 2026-08-11), effective the week of February 16, 2026 (Firstcard — Amazon Visa vs Store Card, secondary source, verified 2026-08-11) — so there is no longer a retroactive interest charge waiting at the end of a promotional window. See what changed and why it matters.

You will not find a customer service number anywhere on this site, for this card or any other. That is a deliberate policy and it follows the same rule as every figure we publish: if we cannot verify it from a primary source, we do not print it. Synchrony’s own site did not respond to us at all, which makes a transcribed number exactly the kind of unverifiable detail we refuse to publish.

There is also an active harm in getting this wrong. Fake support numbers placed where people search for them are a well-documented scam pattern, and a financial site adding one more unverified number to the internet is making that worse rather than better.

Two sources are safe, and you already have both. Your statement, issued by Synchrony directly to you. And the contact details inside your logged-in account, which cannot be substituted by a third party.

If somebody calls you claiming to be Synchrony or Amazon and asks for a code, a password or a payment, end the call and call back using one of those two. No legitimate fraud department will object.
