USATriathlon has an 8 hour delay built into their membership data. This means if an triathlete signs up for a membership on the USATriathlon site, it will take 8 hours until their membership number is available in other applications. This can cause frustration on the part of some triathletes who may be trying to sign up for a race and use the membership number.
We have added an automatic message that explains this when someone is trying to use their membership number when registering as a possible explanation for why it is failing. We simply suggest to try later.
