Domestic billing
1-800-811-1648, listed on UPS's own contact page for domestic billing inquiries. An agent can confirm an account number after verifying who you are.
Account setup
Where a UPS account number actually lives
UPS describes the account number as a unique six-digit number used to identify your UPS account, and it is not the same thing as the username you sign in with. Three places carry it: a UPS invoice, the Accounts and Payment section of a ups.com profile, and a UPS billing agent on the phone if neither of those is at hand. Instructions read from ups.com on 2026-08-28.
Three places to look, in order of speed
- A recent invoice. UPS's own support page points to the invoice as the reference document for the account number, alongside the invoice number, the invoice date and the amount due — the same four fields the UPS Billing Center asks for when you first enroll.
- The ups.com profile. Sign in, click the profile icon in the top-right corner, and open Accounts and Payment. Any account already tied to your login is listed there. To add an account that is not yet linked, choose Add a Payment Method, then Add Existing Account, enter the account number, a nickname, the country and the postal code, and continue.
- Invoice Data Verification. Adding an account UPS does not yet recognize as yours triggers this step: pick Invoice Data Verification and fill in details from any one of your last three invoices. UPS checks the numbers against its own billing records before the account appears in your profile.
If none of that is on hand
Import billing
1-866-493-7140 for shipments crossing into the US, the number UPS lists separately from its domestic line.
General customer service
1-800-742-5877, Monday through Friday 7 AM to 11 PM ET and Saturday 8 AM to 8 PM ET per UPS's contact page, for anything that is not strictly a billing question.
The UPS Billing Center itself is worth bookmarking once an account is confirmed: it holds every invoice, and enrollment only asks for one invoice from the last 45 days plus the account number, invoice number, amount due and invoice date already printed on it.
When a shipper does not need one
A single label bought through a marketplace connector or a shipping tool such as SMKlog is billed against that platform's own UPS account, not a personal one, so nothing above is required just to print one label. A personal account number starts mattering once you want UPS invoicing sent to you directly, a rate history tied to your business, or scheduled pickups set up in your own name rather than a platform's.

Common questions
How do I find my UPS account number?
Check a recent UPS invoice first, where the number appears in the billing details. If nothing is on hand, sign in at ups.com, open the profile icon, choose Accounts and Payment, and either an existing account is already listed there or an administrator can add one using the last three invoices.
What does a UPS account number look like?
UPS describes it as a unique six-digit number used to identify your UPS account, separate from the username used to sign in to ups.com.
What if I do not have a UPS invoice handy?
Call UPS billing support directly: 1-800-811-1648 for domestic accounts or 1-866-493-7140 for import billing, both listed on UPS's own contact page as of 2026-08-28.
Why is UPS asking me to verify with invoice details?
Adding an existing account to a UPS.com profile uses Invoice Data Verification, per UPS's own instructions, which asks for details from any one of your last three invoices as proof that the account belongs to you before it appears in your profile.
Do I need a UPS account number to buy one label?
No. A label bought through a marketplace or a shipping tool such as this site is billed against that platform's UPS account, not a personal one. Your own account number matters once you want the invoice, the rate history and the pickups billed directly to you.
