While season two was on air on Ramadan 2008, it was reportedly watched by 1 on TV9, making it the second most-watched animated series on all of Malaysian television, right behind Doraemon (1.6 mil), yet ahead of SpongeBob SquarePants (800,000). The popularity of Upin & Ipin could have attributed to the commercial success of Malaysia's first CGI-animated feature film, Geng: The Adventure Begins (2009), which featured the twin characters Upin and Ipin, propelling it into the RM 6.31 million mark throughout its seven-week run in Malaysian cinemas as one of the highest-grossing Malay-language films in history.
As the third season reaches its conclusion in late 2009, TV9 reports that Upin & Ipin was viewed by 1.6 million, making it the second most-viewed programme on the channel, just behind the free TV premiere of Geng which was watched by 2.45 million (scoring TVR 12.8).
Indonesia has been the most obvious export market for Upin & Ipin. In 2009, MNCTV which airs the series in the republic reported a TVR of 10.5. Upin & Ipin has also been praised by the Indonesian press; for instance, Fadil Abidin for Analisa who remarked on the vastness of moral content and Islamic values, such as respect for those of different ethnic or religious backgrounds, in a communal setting consisting not only of Malays, Chinese and Indian Malaysians, but also Indonesians.
In March 2010, as the Balinese Hindu community prepare for Nyepi, images of ogoh-ogoh (demonic effigies used for the famed ngrupuk ritual on the eve of Nyepi) which largely resemble Upin & Ipin were exposed on Indonesian media. The effigy reportedly cost 4 million rupiah.
