2 iPhones, 1 iCloud account, determining phone # SMS or iMessage

I have an iPhone 6s and iPhone 6s Plus. The iPhone 6s has a 949 area code and 6s Plus has a 510 area code number. Both iPhones have iMessage turned on and receive the same SMS or iMessage to both phones, it doesn't matter which # is texted, both show the message (I'm guessing due to continuity feature).

Is there a way to find out which number someone messaged? For instance, if someone messages my 949#, I have no way to know which number they texted. Sometimes I will call people back and they don't recognize my number.

Any suggestions? I don't want to setup a new iCloud account for the other phone. It's very nice being able to leave one of the iPhones at home while I go hiking or biking without missing a call or message.

If it makes any difference, one of the iPhones could be jailbroken since I'm still on iOS 10.x which allows the partial tether. Just in case there's an "app for that".

Thank you,

What happens when you get a message from a non-iOS/iCloud/iPhone user? Is the text in blue (indicating an iCloud/iMessage source)? Or green (indicating a message that's come directly from your cellular carrier)? I suspect that using one iMessage/iCloud account across two phones may indicate a bug, not a feature.... so no suggestions.

I don't think it's possible to have two different phone numbers associated with the same iCloud account for iMessage purposes. As far as I know, the phone number that is displayed in iMessage settings can only be the number that the phone reads off the SIM card. Therefore, there should only be one phone number visible in iMessage settings on each device and the phone number displayed should be unique to each device based on the SIM card that's in each phone.

My guess that you have an e-mail address that's associated with your iCloud account set as the default under "Send new messages as" in iMessage settings. Someone is replying to you when you send a message to them, and the message is landing on both phones because both phones are set to receive iMessages sent to that e-mail address.

My assumption is that if someone sends a message (either an iMessage or a regular SMS) to the 949 number, it will not show up on the 510 device, and vice-versa.

I took a few screenshots and uploaded to imgur

Both phones use the same iCloud account. When I go into Settings, Messages and click "Text Message Forwarding" - It will send SMS messages to each iPhone (as long as both are configured to receive the others message). This is only for SMS messages.

For iMessage - I click on "Send and Receive"
You can be reached by iMessage at 510-xxx-xxxx & 949-xxx-xxxx.
"Start New Convesations from"
On the other phone I have the same settings. The only difference is "Start New Conversations from" is selected for that phone's phone#.

The SMS messages are just being forwarded and will allow me to respond from either phone. The iMessage is pretty obvious.

I would just like to know if there's a way I can find out which phone number the person messaged initially. The iMessage one makes it very difficult since it goes through data. SMS I can figure out by turning off one of the phones (because it won't deliver the message if that phone is off)
