ALPCA currently has approximately 2,800 registered members and over 13,100 registered member numbers, although many of the earlier—and therefore lower-numbered—members are now deceased or are no longer members. When an individual joins, he or she is assigned a membership number, which started with #1 in 1954, and are currently being issued in the 13,200 range. Members treasure their "ALPCA number" and often are known as much by the time period in which they joined than by name or geographic home. The club hosts an annual convention each June or July that attracts several hundred members, and regional meets take place in a number of states, provinces, and countries throughout the year. Due to the COVID 19 pandemic the 2020 convention, originally scheduled for Tulsa, Oklahoma from July 8-11, 2020, was cancelled. The next convention, open to members only, will be in Covington, Kentucky, from August 4 to 7, 2021.
