TWIC renewal

Google searching provided some cryptic statements that twics can’t be renewed more than 3 months from their expiration date. However, i couldn’t find that on universal enrollment’s website.

Anyone know if there is a limit on how far from your expiration you can renew?

I recently renewed mine with about 6 weeks to expiration, got it in plenty of time. They informed me to hold the receipt and use it in the event the new card didn’t show up before the original expired.

I thought it was 6 months.
