"What's Your Name, What's Your Number" is a disco song written by Bobby Woods and Roger Cook and performed by the Andrea True Connection. It was released in 1977 as the second single from her second album, White Witch.
The song received a positive review in the Billboard magazine, which described it as "a strong disco/pop crossover tune [with] a subtle sexy treatment". It was moderately successful in the US and the UK, where it reached #56 and #34, respectively. In Italy, it was Andrea's highest-charting single, peaking at #15. She performed the song on the Italian TV program Discoring in 1977. In the same year, Cook also released his own version as a standalone single on Capricorn Records.
