Good to know
Mask Phone Number detects number-like sequences and masks their digits, keeping the count of revealed end digits you choose. It is built to skip things that look like dates or addresses to reduce false matches, and it requires separators or a leading plus so plain counts are not masked. Detection is heuristic, so review unusual formats.
Frequently asked questions
Can I reveal the last four digits?
Yes. Choose to keep the last two or four digits visible, or none at all, depending on what you need to confirm.
Does it avoid dates and addresses?
It tries to. Date-like and address-like number patterns are skipped to cut down false positives, though unusual formats should be reviewed.
Why was a number in my text not masked?
Very short numbers, or bare digit runs with no separators or plus sign, are treated as not phone-like and left alone.
