Your Business Needs Checks. Stop Outsourcing Them.
Every check your business issues carries three critical pieces of information at the bottom – the routing number that identifies your bank, the account number that identifies your account, and the check number that tracks the transaction. These three numbers, printed in MICR format, are what make a check processable by any US bank.
Traditional businesses order pre-printed checks from third-party printers – expensive, inflexible, and slow. OnlineCheckWriter.com eliminates that dependency entirely. Enter your routing number and account number once. The platform prints a complete, MICR line on every check – on blank check stock, from any standard laser printer.
The business impact is immediate: Print what you need, when you need it. Payroll run this afternoon? Print 40 checks right now. Single vendor payment? Print one. No minimum orders. No waiting. No waste.
For businesses issuing checks regularly – payroll, vendor payments, rent, disbursements – the platform pays for itself within the first month.

FREQUENTLY ASKED QUESTIONS
What is a routing number on a check?
A routing number is a 9-digit ABA (American Bankers Association) number that identifies your bank. It appears at the bottom-left of every check and is required for ACH transfers, wire transfers, and direct deposits. Together with the account number and check number, it forms the MICR line that banks use to process check payments.
Can I print a check with my routing number using OnlineCheckWriter.com?
Yes. OnlineCheckWriter.com prints the full MICR line - routing number, account number, and check number - on blank check stock using any standard laser printer. The output is bank-compliant and processes through the US banking system exactly like a pre-printed check.
Do I need a special printer to print checks with a routing number?
No. OnlineCheckWriter.com works with any standard laser printer. You do not need a special MICR printer or magnetic ink cartridge for most banks. Simply load blank check stock and print - the platform handles the MICR encoding automatically.
Is the routing number the same as the account number?
No. The routing number identifies the bank or financial institution. The account number identifies your specific account at that bank. Both appear at the bottom of every check, and both are needed to process a payment.
Can I use OnlineCheckWriter.com without a printer?
Yes. Use the Check Mailing feature for physical delivery (OnlineCheckWriter.com prints and mails for you) or the eCheck feature to send a digital check via email that the recipient can print and deposit at their own bank.
Can I manage multiple bank accounts with different routing numbers?
Yes. OnlineCheckWriter.com supports unlimited bank accounts in a single dashboard. Each account has its own routing number stored securely. When you issue a check, select the account and the correct routing number is applied automatically - no manual entry required.
What is an ABA routing number?
ABA stands for American Bankers Association — the organization that created and maintains the routing number system. ABA routing number and routing number refer to the same 9-digit code printed at the bottom-left of every US check.
Is OnlineCheckWriter.com secure for business check payments?
Yes. OnlineCheckWriter.com uses bank-level encryption, Positive Pay fraud prevention, and role-based access controls to protect your payment data and account information.
