Dialed vs. Dialled
Cambridge marks the verb with -ll- in UK usage and usually -l- in US usage, producing “dialled” and “dialed.” This guide treats the pair as a documented spelling or inflection convention rather than inventing a meaning difference where none is supported.
Use “dialed” in ordinary US English and “dialled” in ordinary UK English.

Quick tests
Meaning / construction test
Is the copy primarily for a US English audience?
If yes: Use “dialed” unless house style says otherwise.
If no: For ordinary UK English, use “dialled”; preserve official or quoted spellings when required.
Caveat: Both spellings are standard regional forms. Treat the choice as a regional or house-style preference, not as a universal correctness distinction.
