Mobile number validation

How eMarketeer validates mobile numbers before sending SMS — country code requirements, character stripping rules, and examples of valid and invalid formats.

Before eMarketeer sends an SMS, it validates the mobile number in the contact's Mobile field. This article explains the rules and shows what counts as a valid number.

How numbers are processed

Before validation, eMarketeer strips every character that is not a digit (0–9) or a + sign. Spaces, hyphens, parentheses, and any other characters are removed automatically. The number that remains after stripping must be a valid mobile number.

Avoid the +46(0) notation. The parentheses are stripped, leaving a 0 between the country code and the subscriber number — this invalidates the number. Use +46 or 0046 instead.

Country code requirement

Every mobile number must include a country code. eMarketeer accepts two international prefix formats:

• A leading + followed by the country code — for example, [phone]
• A leading 00 followed by the country code — for example, 0046733123123

Swedish numbers: Numbers starting with 0 are treated as Swedish numbers and do not require an explicit country code. For example, 0733123123 is valid.

Valid formats

Input	After stripping	Valid
0046733123123	0046733123123	Yes
[phone]	[phone]	Yes
0046 733-123 123	0046733123123	Yes
0733123123	0733123123	Yes — Swedish trunk prefix

Invalid formats

Input	After stripping	Why it fails
46733123123	46733123123	Missing + or 00 prefix
[phone]	[phone]	Stripped parentheses leave a 0 after the country code
733123123	733123123	No country code, and no leading 0 for Swedish numbers
