Encoding Tables

Note that postal codes use only 20 letters; six letters (D, F, I, O, Q, U) are never used. Unused codepoints are indicated with dashes.

00: — 01: — 02: L 03: K 04: M 05: R 06: J 07: A 0: — 1: — 2: 1 3: 3

10: — 11: V 12: — 13: X 14: T 15: — 16: N 17: — 8: — 9: 2 A: 0 B: 4
18: W 19: — 1A: Z 1B: — 1C: P 1D: — 1E: — 1F: — C: — D: 8 E: 9 F: —

No field begins or ends with more than 3 consecutive 1 bits, guaranteeing that there are never more than 6 consecutive 1 bits. Guaranteeing the 5-bit limit on consecutive 0 bits is achieved by limiting the boundaries of the second and fourth fields to 3 consecutive 0 bits, and the first and third fields to 2 consecutive 0 bits:

  • No field contains more than 5 consecutive 0 bits. Code 81, which would contain 6 consecutive 0 bits in field 1 or 4, is not used.
  • Field 1 never ends in more than 2 consecutive 0 bits. Codes that end in 3 or more consecutive 0 bits encode the letters Z or W, which are not used for the first letter of postal codes.
  • Field 2 may begin or end with at most 3 consecutive 0 bits.
  • Field 3 never begins with more than 2 consecutive 0 bits, nor does it ever end with more than 1.
  • Field 4 may begin with up to 3 consecutive 0 bits, and may end with up to 5 consecutive 0 bits, but is always followed by a 1 bit (the alignment bar).

Famous quotes containing the word tables:

    “All my life I have said, “Whatever happens there will always be tables and chairs”—and what a mistake.”
    —Elizabeth Bowen (1899–1973)
