Much like AKB48's previous singles such as "Heavy Rotation", "Beginner" was released in three different versions with five cover variations, with the theater version being exclusively sold in the AKB48 theater in Akihabara, Tokyo. Each version contained a different set list aside from the title track and "Boku Dake no Value". The third track on type A, "Kimi ni Tsuite" performed by Mint, was selected via a fan vote held on Ameba Pigg. In addition, the DVDs attached to all versions except for the theater version each contains three out of the possible six different music videos made for the single: Type A contained formations led by Yuko Oshima, Mariko Shinoda, and the duo of Mayu Watanabe and Jurina Matsui (SKE48), while type B featured formations led by Atsuko Maeda, Tomomi Itano, and Minami Takahashi. The original music video, directed by Tetsuya Nakashima, was found to be too violent to be included with the actual single; and that version was later decided to be released exclusively as a digital download from the day of the single's release.

All non-theater versions of "Beginner" also contain a ballot code that can be used to vote for one's favorite AKB48/SKE48/SDN48 song from all previous singles and theater shows, and the top 100 of that list will become the set list of the four-day marathon concert, AKB48 Request Hour Best 100 2011, which was later held in Shibuya-AX from January 20 to 23, 2011. In addition, all first press limited editions of "Beginner" contain a national handshaking event ticket, and can be used during the later handshaking tour to meet AKB48 members up close and in person. The theater version, on the other hand, contains a ticket to a special handshaking event commemorating the release of the theater version, as well as one photo card of a random member of AKB48.

"Beginner" managed to have 1.03 million copies shipped to retailers before its release, and sold 568,095 copies on its first day. By the end of its first week of release, "Beginner" has sold 826,989 copies and reach top spot on the Oricon weekly singles chart. This meant that Beginner became AKB48's 5th consecutive number 1 single, and has surpassed Speed's 1998 single, "All My True Love", as the best selling girl group single in its opening week on the Oricon. The sale figures also placed "Beginner" as the third best selling single in its debut week by a female artist of all time on the Oricon, behind Hikaru Utada's "Addicted to You", and Namie Amuro's "Can You Celebrate?", which sold 1.06 million and 828,000 copies in their opening week respectively. By selling almost 1 million copies by the end of the year, "Beginner" was the best-selling single of 2010 in Japan.
