Yes, you can block a no caller ID on your iPhone, though the solution is more about silencing than an absolute block. Go to Settings > Phone, scroll down to Silence Unknown Callers, and toggle it on. This will send all calls from unknown numbers directly to voicemail. Keep in mind, this also silences calls from numbers not in your contacts, so you may miss calls from unknown but legitimate numbers.
