Thank u so much

Legend — much appreciated.

Note that on macos 12.1 saving data in contacts.app is broken

Here's an updated version for USA, Canada, and other North American phone numbers. It checks the format and prepends the number with a "+1" where applicable. It also logs what was processed, which phone numbers were already correct with a country code, and which ones were skipped. The log files are saved to the desktop.

As always, make a backup first and modify the file as needed. Test first before using it to make sure it's applying to your use case correctly.

tell application "Contacts"
	repeat with eachPerson in people
		set personName to name of eachPerson
		repeat with eachNumber in phones of eachPerson
			-- Strip parenthesis and dashes
			set theNum to the words of (get value of eachNumber) as text
			-- Remove periods.
			set theNum to do shell script "echo " & quoted form of theNum & " | tr -d '.'"
			
			-- If the number doesn't start with a "+" or a "1" and is 10 digits long, assume it's a USA number.
			-- Prepend it with "+1".
			if (theNum does not start with "+" and theNum does not start with "1" and length of theNum = 10) then
				set value of eachNumber to "+1" & theNum
				my logProcessed("+1" & theNum & " " & personName)
				
				-- If the number doesn't start with a "+" and starts with a "1" and is 11 digits long,
				-- assume it's a USA number and prepend it with "+".
			else if (theNum does not start with "+" and theNum starts with "1" and length of theNum = 11) then
				set value of eachNumber to "+" & theNum
				my logProcessed("+" & theNum & " " & personName)
				
				-- If the number starts with "+" it's already correctly formatted and doesn't need changing.
				-- Log it in "correct" file.
			else if (theNum starts with "+") then
				my logCorrect(theNum & " " & personName)
				
				-- Skipping this phone number as it doesn't fit in the other categories.
				-- Let's log it in the "skipped" file.
			else
				my logSkipped(theNum & " " & personName)
			end if
		end repeat
	end repeat
	save
end tell

-- Add new message to the Processed log
on logProcessed(message)
	logToFile(message, "processedPhoneNumbers.txt")
end logProcessed

-- Add new message to the Correct log
on logCorrect(message)
	logToFile(message, "correctPhoneNumbers.txt")
end logCorrect

-- Add new message to the Skipped log
on logSkipped(message)
	logToFile(message, "skippedPhoneNumbers.txt")
end logSkipped

-- Log a message to a file (file is saved on the desktop).
on logToFile(message, fileName)
	set filePath to (path to desktop as string) & fileName -- AppleScript's write command writes plain text
	try
		set fileRef to open for access file filePath with write permission
		write message & return to fileRef as «class utf8» starting at eof
		close access fileRef
	on error
		try
			close access file filePath
		end try
	end try
end logToFile

@bluestarstudios Great update! I made a couple small changes to add a little more information to logging and allow for dry runs: https://gist.github.com/nquinlan/7d4b5716eb0644dac0af3b97dfc7cc54
