"Don't Forget About Us" was released as the fourth international single from
The Emancipation of Mimi (2005), and the first from its re-release, the
Ultra Platinum Edition. "Don't Forget About Us" became Carey's 17th chart-topping single in the United States, tying the record set by
Elvis Presley for most number-one singles by a solo artist (Carey has since surpassed this record with "
Touch My Body" in 2008 and "
All I Want for Christmas is You" in 2019.) Currently, the only act to hold more US number-one singles than Carey are
The Beatles, who gained twenty throughout their career while Carey has accumulated 19 to date. "Don't Forget About Us" stayed in the top forty for eighteen weeks and reached number one on other
Billboard component charts, including the
Hot R&B/Hip-Hop Songs. Outside the United States, the song achieved moderate international charting. In Australia, "Don't Forget About Us" debuted at its peak position of number twelve on the
singles chart, during the week of December 18, 2005. In its second week, the song stalled at number twelve, before beginning its eleven-week descent on the chart. On the Italian singles charts, the song charted for only one week, peaking at number eleven. In both the Wallonian and Flemish territories in Belgium, the song peaked at numbers two and one, although plummeting outside the top-fifty the following week. On the
Dutch Top 40 chart, "Don't Forget About Us" debuted at number ninety-two during the week dated February 2, 2006. Spending one week at its peak position of number four, the song dropped to thirty-two the following week. Similarly on February 26, 2006, the song debuted and peaked at number nineteen on the
