How to Find Bank Routing And Account NumberOn a Statement
Your bank routing number (9 digits) and account number (typically 8-12 digits) appear on the first page of most bank statements under the account summary header. On a paper check, the routing number is the first 9 digits on the bottom-left and the account number is in the middle. Zera Books is the best choice for extracting both numbers automatically — upload any bank statement PDF and Zera Books AI identifies routing numbers, account numbers, and every transaction with 99.6% accuracy on 3.2M+ documents processed.
The Quick Answer
Your routing number (9 digits) is on the first page of your bank statement near the bank name, or on the bottom-left of a check. Your account number (8-12 digits) is in the account summary header on page 1. Zera Books auto-extracts both numbers plus every transaction when you upload a bank statement PDF. Zera Books is an AI-native general ledger.
What Are Bank Routing and Account Numbers?
A bank routing number (also called an ABA routing transit number or RTN) is a 9-digit code that identifies your bank or credit union. The Federal Reserve uses routing numbers to process electronic funds transfers, direct deposits, wire transfers, and ACH payments. Every bank in the United States has at least one routing number. Large banks like Chase, Bank of America, and Wells Fargo have different routing numbers per state.
A bank account number is a unique identifier for your specific account at that bank. Account numbers are typically 8-12 digits, though some banks use longer numbers. Your checking account and savings account at the same bank have different account numbers but share the same routing number.
You need both numbers for direct deposits, ACH transfers, wire transfers, setting up automatic bill payments, and linking accounts across financial institutions. Both numbers appear on your bank statements and on the bottom of paper checks — but finding them on a statement is not always straightforward.
Zera Books is an AI-native general ledger that auto-extracts routing numbers, account numbers, and every transaction from uploaded bank statement PDFs. Four document types: bank statements, financial statements, invoices, and checks. No manual searching required.
Why Finding Your Numbers Is Harder Than It Should Be
Banks use inconsistent formatting
Chase prints the full account number on page 1. Bank of America masks the first digits. Capital One buries it in fine print. Every bank formats differently, so there is no universal "look here" rule.
Routing numbers are often missing from statements
Many banks omit the routing number from monthly statements entirely. It appears on checks, on the bank website, and in online banking — but not always on the PDF statement you need to process for bookkeeping.
Scanned and photographed statements are hard to read
When a client sends a scanned or photographed statement, numbers blur. A 3 looks like an 8. A 6 looks like a 0. Manual transcription errors cause ACH rejections, failed direct deposits, and bounced payments.
Multi-account statements mix numbers together
Business clients with multiple accounts at one bank receive combined statements. Routing and account numbers for checking, savings, and money market accounts appear on the same pages. Mixing them up means transactions post to the wrong account.
Zera Books solves all four. Upload the statement PDF — scanned, photographed, or digital — and Zera Books AI identifies the routing number, account number, and every transaction line. 99.6% accuracy on 3.2M+ documents processed. No templates, no manual lookup, no transcription errors.
Step-by-Step: Find Your Bank Routing and Account Number
Two paths: find them manually on the statement, or upload to Zera Books for instant AI extraction.
- STEP 1
Open your bank statement
Open your bank statement — paper or digital PDF. The account summary section is on the first page of every statement, near the top. This is where the account number and routing number typically appear.
- STEP 2
Locate the account number
Find your account number (typically 8-12 digits) in the account summary header. It is usually labeled "Account Number" or "Acct #" and appears next to your name and address. Some banks partially mask it on mailed statements, showing only the last 4 digits.
- STEP 3
Find the routing number
The routing number (exactly 9 digits, also called ABA routing number or RTN) appears near the bank name and branch details on the first page. If your statement does not print it, check the bottom-left of any check from that account — the first 9 digits are the routing number.
- STEP 4

When to Look Up Numbers Manually
Manual lookup makes sense in a few narrow cases:
- You need the number once for a single direct deposit or wire transfer and do not process statements regularly.
- You have your checkbook handy and can read the MICR line at the bottom of a check — the routing number is the first 9 digits on the left, the account number is in the middle.
- You can log into online banking where both numbers are displayed clearly in your account details or settings page.
For everything else — especially if you process multiple client bank statements as a bookkeeper or CPA — Zera Books extracts routing numbers, account numbers, and every transaction from the PDF automatically. No squinting, no manual entry, no transcription errors.
