Regex to extract date coy name address

I have a below string. I need to extract date, company name, address, country and postal code from below string:

“4 November 2020\r\n \r\n \r\nMYANT AAA INTERNATIONAL\r\n\r\n10 Aenue Boulevard unit 03-77\r\nPTB 1, P O Box 78\r\nCOUNTRY 800012\r\n\r\nDear”

Are the information always in the same order? If not, how do you tell what is what?

Yes in same order

Then you could just use String.Split to get the information.

arrayInfo = infoString.Split(Environment.NewLine.ToCharArray, StringSplitOptions.RemoveEmptyEntries)
strDate = arrayInfo(0)
strCompanyName = arrayInfo(1)
strAddress = arrayInfo(2) + Environment.NewLine + arrayInfo(3)
arrayConPos = System.Text.RegularExpressions.Regex.Split(arrayInfo(4), "(?<=\w) (?=\d)")
strCountry = arrayConPos(0)
strPostalCode = arrayConPos(1)
