What is 312-523-9300 and Why Are People Talking About It?

Lately the phone number 312-523-9300 has surfaced in online forums, caller-ID reports and scam-alert databases. For people who have received calls from it, the experience has ranged from unwanted telemarketing to alleged threats. At the same time, there is a connection drawn by some to the website Selmantech (selmantech.co.uk) — which complicates things and warrants a closer look.
The Selmantech Angle
The site Selmantech – “selmantech.co.uk” – positions itself as a tech/business lifestyle blog covering subjects like digital privacy, home improvement, real estate and technology. For example, one of its articles is titled “Understanding the Need for Digital Privacy in an Era Where the Internet Has Become an Integral Part of Daily Life”. selmantech.co.uk
What’s notable: despite covering tech/business topics, I did not find a clear, verifiable “about us” section, or transparent business contact information on Selmantech that ties it unambiguously to the number 312-523-9300. In other words: the number is mentioned in calls from users who associate it with aggressive marketing or scam-calls; the site itself doesn’t clearly disclaim or confirm any such activities.
What’s Reported Online About 312-523-9300
Multiple independent sources suggest strong red flags:
- The caller ID / spam-call aggregator tool RoboKiller shows 312-523-9300 with a “Scam” rating. It reports 206 total calls, 6 user reports, and frequent abuse scenarios. For example, one user report says: “Told me I need to take out a bank loan and never pay it back because the bank will never do anything.” Robokiller Lookup+1
- A thread on 800notes likewise lists reports of harassment, threats and debt-collection style claims from the number. 800notes.com
- On a Facebook group post, a user reported: “Got a phone call with this number today +1 (312) 523-9300. They claimed they were with Bank of America and suing me…” Facebook
In short: while there is no definitive legal case publicly linking 312-523-9300 to a specific firm (from publicly available data I found), the consensus from user reports is that it is very likely a scam or nuisance call source.
How This Relates (Or Doesn’t) to Selmantech
Given the frequent association, it’s worth looking at how Selmantech’s content, structure and approach may tie in (or not) with the chatter around 312-523-9300.
Selmantech’s Purpose & Content
From the home page: Selmantech presents itself as a general blog covering business, health, home improvement, real estate, tech, etc. For instance:
- The menu lists categories like Business, Health, Home Improvement, Real Estate, Tech. selmantech.co.uk
- One of the recent posts: “Why Local Brands Trust Denver Digital Marketing Services”. selmantech.co.uk
- Another: “Some Of The Very Best Hyderabad Travel Attractions”. selmantech.co.uk
So the site is broad and not specifically a scam alert or number-lookup site.
But What’s Missing
- There’s scant clarity about the organization behind Selmantech: who runs it, where it is based, contact info.
- The site lists seemingly random “business contact numbers” inside its article listings (e.g., June 27 2025 list of hotline numbers). selmantech.co.uk
- I did not find any explicit article on the site about “312-523-9300” or a dedicated investigation into that number.
The Possible Connection
Given the above, one plausible explanation:
- It might be that callers using the number 312-523-9300 (or a spoof) reference “digital marketing services” and thereby attempt to connect to or leverage blog-/content-platforms like Selmantech.
- Alternatively, the number may simply appear in user reports and has no legitimate tie to Selmantech, yet gets mentioned together because some calls claim to represent “digital marketing” or “business growth” services (which ties loosely to Selmantech’s tech/business motif).
- Because Selmantech has many posts about business services, digital marketing, contact numbers etc., recipients of calls may believe the call is related to such a site.
At this time, the safest assumption is: No verified connection between Selmantech and 312-523-9300 can be established from publicly available sources. That means we should treat them as distinct until proven otherwise.
Why Is 312-523-9300 Flagged as a Scam? What Tactics Are Reported?
When it comes to phone numbers flagged as “scam”, reports often involve a few recurring patterns. Let’s go through what the user-reports say for 312-523-9300, and how readers can defend themselves.
Common Strategies Reported
- Urgent Threats & Pressure
A frequent report: the caller claims you owe money or your business is at risk of being shut down. For example: “He asked for the owner and told me that I won’t have a job in a month.” Robokiller Lokup+1 - Impersonation of Official Entities
Some calls allegedly claim to be representing major institutions (e.g., banks such as Bank of America). “They claimed they were with Bank of America and suing me…” Facebook - Insistence on Speaking to “Owner” or Key Decision-Maker “He instantly said you are blowing money on all these Google ads… when I confronted him he hung up.” Robokiller Lookup+1
- Spoof-friendly Techniques
The number may appear local (in this case Chicago’s 312 area code), which may give it a veneer of legitimacy. The call may appear on caller ID as “(312) 523-9300”.
Why These Tactics Are Dangerous
- Psychological pressure: urgency and threats cause people to act without full deliberation.
- Expertise illusion: claims of being from a bank or government raise undue trust.
- Local number familiarity: calls from local area codes are often answered more readily than long-distance ones.
- Asking for owner/decision-maker: focuses on someone without intermediary filtering, increasing success rate.
What the User Reports Suggest Specifically for 312-523-9300
- A large number of reports in the RoboKiller system (206 calls, 6 reports) flag it as “Scam”. Robokiller Lookup
- Online log writers at 800notes describe extremely aggressive language, threats against business or personal safety. 800notes.com
- Some mention the caller hung up when challenged or asked for details. Robokiller Lookup
What Should You Do If You Receive a Call From 312-523-9300?
If you get called from this number (or similar), here are steps and best practices to protect yourself.
Don’t Panic, But Stay Alert
- First, do not automatically assume legitimacy just because the caller ID shows a local number. Caller ID can be spoofed.
- Take a breath. Scammers rely on haste and fear.
Ask Questions & Verify
- Ask: “Which company are you calling from? What’s your job title? Can I call you back?”
- If they claim to be from a bank, utility, or government: hang up and call the official number listed on your statement or website. Do not use the number they provide.
- Never give personal or business financial details (account numbers, SSNs, bank login info) on an unsolicited call.
Document the Call
- Write down date, time, what was said, caller ID, number (312-523-9300).
- If threats were made, consider a screenshot or recording (if legal in your jurisdiction).
- Report the call to your local consumer protection agency or the telecom provider.
Block/Report the Number
- Use your phone’s block option to stop further calls from the number.
- Add the number to a spam-call blocking service (e.g., RoboKiller, Truecaller).
- If you’re in the US, you can forward unwanted calls to the FCC’s complaint line.
Educate Your Organization (if a Business)
- If you run a business and your staff receive such calls, train them: they should not engage, provide details, or transfer to owner without verification.
- Institute a verification-first policy: if a caller claims urgency, route them through a known official number.
Why Does the 312 Area Code Matter – The Chicago Angle
The number 312-523-9300 falls under the 312 area code, which covers downtown Chicago, Illinois. This can influence how the call is perceived:
- A local number (312) may make the call seem more “real” to a Chicago-based recipient.
- Many scam operations use local area codes to increase pick-up rates; psychological studies show people are more likely to answer a call if it appears local.
- For businesses and individuals in the Chicago region, a call from 312-523-9300 might seem legitimate (like a vendor, marketing firm, or service provider you might know). That’s why awareness is key.
Has There Been Any Legal or Formal Action Against This Number?
From available public information:
- I did not find a court case, state attorney-general action or BBB listing specifically for number 312-523-9300.
- The site Selmantech does not appear to publicly claim it operates this number (at least not obviously).
- The lack of formal public action doesn’t mean it’s safe; it may mean the operations are offshore, unregistered or difficult to trace.
Thus, even without formal action, the sheer volume of user-reports and consistent pattern of scam-behavior is enough to warrant caution.
How to Approach Selmantech (and Similar Sites) When You See a Call Like This
Since Selmantech was referenced at the beginning of this post, it’s worth reflecting: how do you deal with blogs or content websites when phone-calls connect to them (or appear to)?
Evaluate the Site’s Transparency
- Does the site list a physical address, registration, ownership?
- Are business offers clearly explained, with credentials, reviews, contact info?
- Are promotional offers or “free consultations” backed by clear terms?
Be Wary of “Free Audits” or “You’re Spending Too Much”
Some callers claim you are “wasting money”, “spending too much on ads”, or “not optimizing your business”. These lead-in phrases often serve to hook you into a pricey consulting arrangement. If a call begins this way, that is a warning sign.
Match Calls to Site Content
If you get a call from someone referencing Selmantech (or a similar site) and they claim to represent that entity, go to the website and check:
- Is there a staff directory or team page?
- Is the phone number the same?
- Does the site mention consulting services and fees clearly?
If you cannot find this easily, treat the call with suspicion.
Always Get a Written Proposal
If a service is offered, ask for an email with written scope, pricing, expected outcomes, cancellation policy. Legitimate firms will provide this. Scammers often rely on verbal pressure and ask for payment quickly.
Final Thoughts: Why This Matters
In today’s environment of remote work, digital services and global business contacts, phone scams continue to evolve. Here’s why being aware of numbers like 312-523-9300 matters:
- Protection of time & money: Responding to a scam call can waste time, disrupt your business operations, or lead to financial loss.
- Maintaining trust: If a business picks up a scam call and acts on it, their clients/employees may lose faith.
- Psychological impact: Threats, high-pressure calls and impersonation create stress and distraction.
- Regulatory risk: If you inadvertently engage with a scammer and then claim services, you might be liable for fees or unwittingly participate in unlawful setups.
By staying cautious, one call (from 312-523-9300 or similar) does not have to turn into a major incident.
