Powerful-Opinion-989's journey

I was laid off from my position at a company about a year ago, and recently I received an email from them asking me to send my employee ID for potential job opportunities. I'm feeling confused because they let me go without any explanation, and now they seem interested in my profile again. I’m not sure if I should respond and provide my ID or if this is just a generic outreach. I could really use some advice on how to handle this situation.
