Validate Your USA Lacrosse Number

The USA Lacrosse Ping checks several things from our software against its database. This does not save the USA Lacrosse Number into your records. If you would like to keep that on file, you will need to ask for it in an additional form field.

The validation points are as follows:

  • Child’s First Name

  • Child’s Last Name

  • Child’s Birthdate

  • Child’s Zip Code

  • Email Address on file
  • The US Lacrosse Number

  • The Expiration date, against the end date of the program (child cannot have the USA Lacrosse number expire before the program ends)

Step 2:
