Search the official USBC Approved Ball List by the ball's exact brand and model before certified competition; USBC updates the list weekly. Approval on that list does not clear every model for every tournament, so also check the event's ineligible-ball list and have a pro shop confirm the ball's identity, drilling and condition.
Before using a ball in a USBC-certified league or tournament, check its exact model on the USBC Approved Ball List. The list is updated weekly. A current entry confirms the model’s listing status; it does not confirm that a particular used ball is intact, correctly identified, drilled for your hand or eligible in every event.
Check the model and the event
Search by brand and full model name, including a colorway or variant when the maker distinguishes one. Confirm the spelling against the ball’s label or the manufacturer’s product page. If the name does not appear, do not infer approval from a similar model; ask the pro shop or the event official.
Some events apply additional restrictions. USBC maintains separate national tournament ineligible-ball lists, so check the list for the event you plan to bowl. USBC’s approved-ball document also says that models made before the list began in January 1991 were previously approved, but their acceptance is left to the league or tournament official. House balls are covered by a separate exception in that document.
Inspect a used ball before paying
| Check | What to verify |
|---|---|
| Brand and model | Match the ball’s original name and markings to the official list and manufacturer’s page. |
| Serial and identification | Confirm that markings can be read and match the ball’s identity. USBC announced a change effective January 1, 2027: identification markings may not be re-engraved. |
| Holes and plugs | Ask a qualified pro shop to assess the drilling, plugs and whether a new fit is practical. USBC permits plugged balls, subject to its specifications. |
| Surface and condition | Look for damage or wear that may affect use; compare the surface with the maker’s maintenance instructions. |
| Fit and weight | Check the ball against your span and pitch with a pro shop. Review bowling ball weight and span, pitch and grip fit. |
USBC’s August 2026 rules update says the identification-marking change starts January 1, 2027. If a ball’s status or markings are uncertain, ask the league or tournament official before using it. For a new bowler’s equipment order, see what to buy first. Browse pro-shop tools and services.

Common questions
Does a USBC-approved bowling ball qualify for every tournament?
Not necessarily. Some USBC national events publish a separate ineligible-ball list. Check the exact tournament rules as well as the Approved Ball List.
What if an older ball is not on the approved list?
USBC says balls made before the list began in January 1991 were previously approved, but acceptance is at the discretion of the league or tournament official. Ask before using one.
Can I use a used bowling ball in a certified league?
Check the exact model's status and ask a pro shop to inspect its identification, holes, plugs and fit. A model listing does not establish the condition or fit of one used ball.
Are bowling ball serial numbers changing in 2027?
A USBC August 2026 rules update says that starting January 1, 2027, identification markings may not be re-engraved and balls with re-engraved or unidentifiable serial numbers are not allowed in certified competition.
