Account Number Sequence Check

Check the chart of accounts for duplicate numbers and gaps in the sequence. Preparation only, not an account action.

What to provide

The chart of accounts with account numbers and names.

How it works

1. List the accounts and their numbers.
2. Sort by number.
3. Mark duplicate numbers and unexpected gaps.
4. Return the check without ledger changes.

The output

account | number | duplicate | gap_before | verdict

Worked fictional example

Fictional chart holds 120 accounts; 2 different expense accounts both carry the number 6100: 2 accounts sharing 1 number, so postings split unpredictably.

Checks and limits

Keep original values, source IDs and version dates. Unknown facts stay held. Use qualified review for hiring, legal and accounting conclusions. No send, share, sign-in, scheduling, ledger change or payment. Fictional contract review is not a live account compatibility test.
