Which part of town has which code
We do not publish which of these codes covers which street or neighbourhood in Salisbury, and we would rather say so than guess. Area codes are drawn around telephone rate centres, which follow neither municipal boundaries nor ZIP codes, and the per-ZIP telephone data we hold is a 2018 snapshot too noisy to split a city with. Where these codes overlay one another the question has no answer at all: they cover the same ground by design. Awaiting a current, clean-rights rate-centre boundary source.
ZIP codes for the same city
Postal geography is organised separately from telephone geography, so Salisbury’s 4 ZIP codes do not map onto the codes above. They are listed in full, with the county each falls in, on the postal side of the site.
