Received an anonymous letter in Brazil. No sender, only a postal label

Unfortunately, this subreddit doesn’t allow image attachments. If anyone is willing to help, I’ll share photos of the envelope, the label….

I was able to decode the Data Matrix code on the label, which gave me a numeric code, but I have no idea what to do with it next or whether it can be used to identify where the letter was sent from or who mailed it. Any guidance would be greatly appreciated.

Can anyone with experience in document analysis, Data Matrix codes, or postal labels help me identify who sent this anonymous letter?

Unfortunately, this subreddit doesn’t allow image attachments. If anyone is willing to help, please send me a DM and I’ll share photos of the envelope, the label, and the handwriting.

recebi uma carta anônima sem remetente

A carta foi impressa, não tem remetente, veio só um selo com um qr code e o código não é padrão correios, alguém sabe me dizer como descobrir algo com esse código e se é possível?
