What an issuer's "inactivity review" actually checks

Every major credit-card issuer runs an automated scan, usually monthly, that checks every consumer account for inactivity and flags ones at risk of closure. If your unused cards are sitting at $0 balance with no recent charges, this is the machinery deciding their fate. Knowing what the scan checks tells you exactly what you need to do to pass it.

The four signals an inactivity review checks

Every issuer's review uses some combination of the same four signals. Weighting differs; shape is consistent across the industry.

1. Date of last posted transaction

The dominant signal — by far. The query picks the most recent posted transaction and computes how many days have passed. If that number exceeds the issuer's threshold (typically 12 months for consumer cards), the account fails.

Two details matter. The transaction must have posted, not just been authorized — pending, declined, or reversed transactions don't count. And it must be a charge, not a payment. Issuers track outbound merchant transactions, not the inbound payments you make to clear the balance. A $1,000 payment on a $0 balance doesn't move the needle.

2. Statement balance trend

Secondary. The review looks at the last 6–12 statement balances and asks: was there activity? If every statement shows $0.00 across the window, that supports the flag. One non-zero balance somewhere in the window is evidence of a real account even if the most recent statement is $0.

3. Credit-limit utilization across the portfolio

Some issuers (notably Chase and Citi) factor in your overall relationship. Three cards with the same issuer, two used heavily, one dormant — they're more likely to close the dormant one because they already have plenty of relationship through the others. A single dormant card with no other products is more likely to stay open in case you convert later.

4. Customer-relationship value

How long you've been a customer, premium products held, FICO trend (where available), partner products like checking. A 15-year customer with a clean history gets longer leeway than a 1-year customer. The review isn't blind to context — it just doesn't share its weighting with you.

What the review does NOT check

Three common assumptions that don't matter:

• Whether you logged in. Engagement metrics aren't part of the query. The review looks at posted transactions.
• Whether you called customer service. The rep can note the call, but the automated review doesn't read notes.
• Whether you made a payment. Payments are credits, not charges. Paying off a $0 balance is one of the most common misconceptions about keeping a card alive.

How to pass

One posted charge inside the issuer's window. The size doesn't matter — $1 and $1,000 produce the same boolean (date < threshold = pass). Three durable approaches:

The subscription anchor

Pick a recurring subscription you already pay for and put it on the dormant card. Set autopay. The review finds a charge in the last 30 days every time. Best for 1–2 unused cards. Becomes unwieldy at 4+ — you lose track of which subscription is on which card, and any cancellation creates a quiet inactivity gap.

The quarterly manual charge

One small purchase per unused card every 90 days. Coffee, a song, a digital download. Pay it off the same day. Free, but requires you to remember and execute. Best for 1–3 disciplined cardholders. Fails quietly when life gets busy.

The automation approach

A service that runs a tiny authorized charge on each card on a schedule. The mini-charge strategy — one posting per card per month, no spending required. Best for 3+ unused cards or anyone who'd rather not think about it.

What happens if you fail

The flag-to-closure pipeline:

1. Flagged. Account marked for review-board attention. Bank of America explicitly labels this status "Inactive" in the customer app — open but on watch.
2. Decision. Within ~30 days, a human (or another automated step) reviews flagged accounts. Outcome: close, downgrade to a no-fee product, or leave open with a credit-limit reduction.
3. Notice (optional). Capital One and Discover routinely send 30-day notices. Chase, Amex, Citi, and BoA often don't. The notice says "make a purchase by [date]" to prevent closure.
4. Closure. If no action, closure goes through. Your credit report shows "Closed by credit grantor" within 30 days.

If you've been flagged but not yet closed, one posted charge usually clears the flag at the next review cycle. Move fast — once the closure has been processed, reactivation is much harder than prevention was.

Bottom line

An inactivity review is a database query, not a moral judgment. "Has this account had a posted transaction in the last X months?" The answer determines what happens. You don't need to know the exact threshold to defend yourself — keep at least one transaction posting per quarter on each card you want to keep, and the review returns "active" every cycle.

The simplest way to do that across multiple cards is to delegate the cadence to something that doesn't forget.
