Some TWICs Won’t Work in Readers

Posted to Maritime Transportation Security News and Views (by on December 6, 2011

Some 26,000 Transportation Worker Identification Credentials (TWICs) may be rejected by TWIC reader machines because of defective encoding. At some point recently, the Transportation Security Administration (TSA) posted on the “Latest News” portion of its TWIC website that some previously issued TWICs had been improperly coded.

Some 26,000 Transportation Worker Identification Credentials (TWICs) may be rejected by TWIC reader machines because of defective encoding.  At some point recently, the Transportation Security Administration (TSA) posted on the “Latest News” portion of its TWIC website that some previously issued TWICs had been improperly coded.  This short statement included links to FAQs concerning the issue and a list of affected Agency Serial Numbers (ASNs).

Cards with the affected ASNs had their integrated circuit chips encoded with Federal Agency Smart Credential Numbers (FASC-Ns) that were missing at least one digit, “causing readers to not recognize the card as a valid TWIC.”  The “production system error” causing the problem was corrected on April 5, 2011.  As a result, TWICs issued before that date could have this problem, and “TWIC readers could have problems reading these cards.”  TSA estimates that only about 26,000 TWICs (of more than two million) are affected and they will replace these cards for free.

How does this impact you?  If your place of employment uses TWIC readers and your TWIC has a truncated number, you probably are experiencing problems getting to work and need a new TWIC ASAP.  If your employer is waiting for the Final TWIC Reader Rule before investing in the machines, your TWIC will probably expire before you have to use it in a reader and  your new TWIC won’t have the problem.

How do you tell if your TWIC is missing a digit?  Your card’s ASN is an eight digit number at the bottom left below the large bar code on the back side (and not the eight digit number at the top right of the card, to the right of the small bar code).  Compare this number to the ASN list.  If your number comes up and you need, or want, to go through the replacement process, call the TSA Help Desk at 1-866-347-8942 (MON-FRI, 8AM to 10PM Eastern Time).  Tell them that your TWIC “has a truncated FASC-N” and they’ll tell you what to do.  You’ll need to pick a TWIC Enrollment Center where you’re going to pick up your replacement card and you’ll need to surrender your defective TWIC when you go.

A TWIC notification bulletin dated “November 2011” lays out everything quite clearly, including a picture, reproduced below, showing you where to find you ASN.
