New ARRT ID Numbers Will Be Seven Digits

As ARRT approaches its 100th anniversary, the number of R.T.s and candidates for ARRT credentials continues to grow. More than 335,000 professionals now hold at least one ARRT credential. That number, combined with past candidates and people who once had ARRT certification and registration, means that we’re close to running out of six-digit identification numbers.

Beginning no later than 2020, we’ll change to a seven-digit identification number. All newly assigned identification numbers will begin with a 1, such as 1000027.

Your existing six-digit number won’t change. We’re letting you know because some of our partners might have to change their ID fields to accommodate the new numbers. For example, if you register for a conference, you might see seven spaces for your ARRT ID number.

In such a case, leave the first space empty if your ARRT ID number has only six digits.
