League Age Definition for 2018

For the 2018 season, a player's league age is determined by his/her age on August 31, 2018, with the exception of those born during May-Aug 2005 that have a league-age determination date of April 30, 2018. A player's league age may be different than their current actual age.

Those players with a birthdate within May-Aug 2005 are grandfathered in as league-age 12 year olds for the 2018 season, as discussed in this letter from Little League: Update to the Implementation of Little League Baseball Age Determination Date.

Acceptable Forms of Proof of Birthdate

Per Little League International rules and regulations, players are only eligible to play in Allied Gardens Little League if a proof of birthdate for the player has been shown to the AGLL player agent(s) or president. The acceptable forms of proof of birth date are:

  1. Original proof of age document (e.g., original birth certificate), if issued by federal, state or provincial registrars of vital statistics in the country in which the Little Leaguer is participating.
  2. If country of participation differs from the country of proof of age document, original proof-of-age document issued by federal, state or provincial registrars of vital statistics, or local offices thereof, are acceptable proof of age, provided the document was filed, recorded, registered or issued within one (1) year of the birth of the child.
  3. An original document issued by federal, state or provincial registrars of vital statistics, or local offices thereof, listing the date of birth, with reference to the location and issue date of the original birth certificate, is acceptable. (The original birth certificate referenced must have been filed, recorded, registered or issued within one (1) year of the birth of the child.) Also issued by these agencies are photocopies of the certificated of live birth with the certification also photocopied, including the signature, and include the seal of impressed thereon. Such documents are acceptable without “live” signatures, provided the original filed, recorded, registered or issued date of the birth certificate was within one (1) year of the date of birth.
  4. For children born abroad of a parent or parents who are U.S. citizens, any official government document issued by a U.S. federal agency or service, is acceptable. For military dependents, Department of Defense identification cards and military hospital certificates are acceptable. These must be originals, not copies, and must refer to a filing, recording, registration, or issue date that is within one (1) year of the birth of the child.
  5. A "Statement in Lieu of Acceptable Proof of Birth" issued by a District Administrator is acceptable.

NOT ACCEPTABLE AS SOLE PROOF OF BIRTH: Baptismal Certificate; Certificate of Blessing; Certificate of Dedication; Certificate of Circumcision, etc.; Hospital Certificate; photocopied records.
