"The white signs are identifying labels that appear on a step riser, usually close to the middle or top of the staircase. The short code on each label reveals the staircase's location. An "M," "S," or "P" are always the first letters to appear in the code. "M" stands for mezzanine, "S" stands for street, and "P" stands for platform, indicating which level the staircase can be found."
"The number in the middle of the code identifies which specific staircase you're on within the station. Since the stairs in the photo below are labeled with a "7," we know there are at least seven staircases in that station. The final letter, "A," "B," or "C," will identify the "channel" of the staircase in cases where it is wide and has multiple sections. In the photo above, the channel on the left is labeled "P4A," while the right side is labeled "P4B.""
The tiny white signs on subway stair risers are identifying labels that show staircase location. The first letter in the code—M, S, or P—indicates mezzanine, street, or platform level. The number in the middle identifies the specific staircase within the station. A final letter such as A, B, or C designates the channel for wide staircases with multiple sections. Labels like P4A and P4B distinguish adjacent channels of the same stair. MTA workers use these codes for internal wayfinding and maintenance reporting. Riders can also use the codes to give or follow precise directions.
