As of my last update, the LEGO set numbered 5003489 does not correspond to a specific, well-documented LEGO set in the extensive catalog of LEGOs releases. LEGO has produced thousands of sets across various themes ranging from cityscapes, fantasy worlds, space exploration, to movie-based sets and much more. Each set is uniquely numbered to help identify it, and the numbers can sometimes be re-used in different regions or for promotional items, which can create confusion.
However, if 5003489 refers to a promotional item, an accessory pack, a limited edition release, or was newly announced, I recommend checking the official LEGO website or trusted LEGO fan sites for the most accurate and up-to-date information. LEGO continually releases new sets and retires old ones, making their catalog a dynamic and ever-expanding universe of creative possibilities.
