1963 Peruvian Segunda División

All teams faced each other in a double round-robin format, playing home and away matches. The team that accumulated the highest number of points at the end of the season was automatically crowned champion and promoted to the Peruvian Primera División, while the team with the fewest points was relegated to the Ligas Provinciales de Lima y Callao.

Two points were awarded for a win, one point for a draw, and no points for a loss.

ADO, as champions of the 1963 Liga Provincial del Callao, and Santiago Barranco, as champions of the 1963 Liga de los Balnearios del Sur, were supposed to play a final to determine promotion to the 1964 Segunda División.

The champion of the 1963 Liga Provincial de Lima did not take part in the tournament due to its disagreement with the decision of the Peruvian Football Federation to include the champion club of the Liga Distrital de San Isidro in the Liguilla de Promoción tournament to the 1964 Peruvian Segunda División.

As a result of this situation, the Peruvian Football Federation decided to annul the Liga Provincial de Lima tournament.

ADO earned promotion to the 1964 Segunda División.

Alongside the Second Division championship, a reserve teams tournament was held, featuring the reserve teams of the participating clubs.

Porvenir Miraflores and Atlético Chalaco reserve teams finished level on 7 points each after the nine rounds, which required a playoff match to break the tie. Porvenir Miraflores went on to win the decider 4–1.^[7]
