How to find a word/phrase in a line using PowerShell? - string

Question

I have been at this for days now but can't seem to figure it out.
I am trying to compare values(PartNumber) from the database to the first line of the text file. If the PartNumber exists(in the first line of the file) display a message "Part Number Matches" if it doesn't send an email.
The issue is that I get messages saying parts do not match when they are clearly the same.
All wrongly mismatched part numbers have a letter in the beginning for ex. D78948, C56234, etc. At first I thought maybe it is because the part number is alphanumeric. But then the parts that are correctly matched are also alphanumeric.
The PartNumber in the terminal is the one from the database.You can clearly see from the picture that the part number from the database and the one in the text file are exactly the same but the check still fails.
Instead of If (Get-Content -Path $fullPath -TotalCount 1 | Select-String -Pattern $partNo -AllMatches) I have tried
If($eiaContent -like "*$partno*") ,
If($eiaContent | Select-String -Pattern $partno)
But none of them seem to work.
Any help is appriciated!
